T0 @213 whom it may concern.-

Be it known that we, CHARLES MUsKER, ARTHUR MUsKER, and WILLIAM GEORGE HAY, subjects of the Queen of England, and residents of Bootle, in the county of Lancaster, England, have invented certain new and useful Improvements Connected with Oil- I-Ieated Steam-Generators and other Apparatus, of which the following is a specification.

This invention has reference to the generation of steam by oil fuel or liquid fuel on autovehicles in which the motor fluid for driving them is steam; but parts of the apparatus or novel characteristics of the invention are also applicable for use for the generation of steam for other purposes. For convenience of description, however, the invention will be described as applied mainly in connection with an autovehicle steam-generator.

The class of oil-heated apparatusto whichthis invention relates is that in which the oil is vaporized or gasified and the vapor or gas burned as it is produced, the vaporization or gasification being effected at or in the burner or furnace to be heated.

The invention will now be mainly described in its application to the heating of steamgenerators, and more especially of the type in which only a small quantity of water and steam is contained, such as. are proposed-for use in connection with autovehicles.

In the drawings, Figure 1 is a longitudinal section showing a burner attached to a steamgenerator of the type referred to; and Fig. 2 is a cross-section through the burner, half taken at the line A A and half at the line B B.

This apparatus comprises a chamber or part in which the oil is vaporized, a part in which the air used to support combustion of the gases or vapors of oil is heated, and a burner portion proper.

In the drawings the oil vaporizing or gasifying chamber is designated a-,and it isformed by an outer circular wall a, an inner annular wall a an end wall a and an end cover a, bolted on the ends of the walls a a The chamber is thus annular. The air-heating chamber is designated 6 and is of similar form to a, its outerand inner walls b b being substantially continuations of ct and a respectively, while the outer wall 17 closes one end and-the other end being closed (except at the upper part where it communicates with a)'by the wall a This wall a constitutes a partition between the chambers (36 and b. The communication between the chambers 19 and a is at the highest part and is made by a portion of this wall being cut away. The entrance of air to the chamber b is bvthe branch 19 at the bottom of this chamber, this branch being connected with the source of supply of air. W'ithin the chamber 1) there are thin annular ribs which convey heat from the burner within the wall 19. to the air as it passes through the chamber 1). The oil say ordinary petroleumis introduced into the chamber a through the pipe 0, entered through the top of the outer walla, and falls onto the upper part of the wall a Within the chamberc there are a series of partial partitions a extending out from the walls a and a alternatelyand also ext-ending radially from'the inner wall a to the outer wall at. These partitions cause the oil and air to flow in a circuitous course through the chamber a. l

. Within the wall a at the front end of the burner there is a chamber d," closed at one end by a bolted-on cover (1 and having a perforated wall d at the other end. The perforations in this wall are numerous and are in the form of tubular passages of small diameterarranged closely togetherthat is, they are relatively small in diameter and relatively long. This proportion is conveniently provided by making this Wall d of thick metal and drilling or coring out the holes through it. In the front end of this wall there is inserted a gauze diaphragm d for the purpose of insuring that no back-firing shall take place, and a second wire gauze diaphragm.

d may also be provided.

In front of the wall 61 there is a perforate block 2 of iron or fire-resisting material for breaking up the flame-jet and obstructing its flow, thereby reducing its velocity and increasing its heating action in the steam-generator. It also assists in obviating noise in the combustion.

The chamber a communicates with the chamber 01 by an opening at d in the bottom 01": the wall a and communication between the outside of" the burner and the space in front'of the wall d is by means-of a tube-f, which passes through a cover 01 and the wall d and is provided with a cap f. By removing this cap and introducing a kindling devicethe combustiblefluidissuing-through the wall d "is ignited.

fIn the drawings, it represents the watertubes of the steam-generator to be heated by the burner,'three coils being shown. Outside these'coils h and also the chambers a and b there is a casingiof a non-conducting" oharacter- -say asbestos held betweentwo sheet-plates At the bottom, beneath the chamber a, there isa removable coverj,

while at the upper part, over the chamber 1),
